PATENT OFF ICE DUMMY PRACTICE-RIFLE.

Application led. March 12, 1917. Serial No. 154,302.

To @ZZ iozom'fit may concern.'

Be it known that I, ROBERT EDWIN REAR- DoN, a subject ofthe King of Great Britain, residing in the city of Ottawa, in the Province of Ontario, Dominion of Canada., have inventeda new and useful Improvement in Dummy Practice-Rifles, of which the followinc1 is a specification.

y Apresent invention relates to improvements in dummy practice guns designed for practice in shooting at miniature targets and preferably with dummy cartridges.

One object of the invention'is to provide a :dummy practice riiie or gun complete in itself as an article of manufacture and having incorporated therein asa unitary part thereof a projectable rod capable of co-acting with a miniature target, which rod will be projected a material distance by the tiring act, and will be instantly returned or retracted into the barrel.

Anotherobj ect is to vprovide a dummy gun which may be manufactured atminimum cost'andby the use of whichthe user may become an expert marksman at no expense forammunition. i

A further object is to provide a gun oit' this character capable of all the practice use of a regulation gun, Ybut which will be pro vided with means for preventing the accidental, use of a live cartridge, and a still further obj ect is to provide improved means for marking the target to indicate the point struck.

lVith these and other objects in view the invention 4includes the novel features of construction and arrangement and combination of parts'hereinafter described ,my said inventiony being delined by the appended claims.

An embodiment or' my invention is illustrate'd in the accompanying drawings in which 4 Figure 1, is a. partial vertical longitudinal section through my improved dummy gun.

away and `with parts omitted.

F ig. 3 is a section. on line SW3 of Fig. 4: is a detail view andi, i j

Figs.` 5 and 6 are detail views of modifications. 1 l

It will be understood that/my dummy riiie is intended to be used with a miniature target, preferably of strip form, carrying two hullsi eyes, one for sighting and the other for receiving the impact of the projectable rod.

Referring by reference characters to this drawing the numeral 11 designates the main portion of the dummy. gun which includes the stock `12, the fore stock 13, barre-l cover 14, and barrel 15.

Within the barrel' and 'forming a permanently connected partthereofis a proj ectable rod 28 which is designed, to be projected for a material distance to strike the target and to be instantly retracted within the barrel in position for a second tiring. As it is desirable to form the barrel .of some material other than metal, I prefer to line the bore 17 thereof. with a metal tube indicated at 18 which may have its rear end threaded as at 19 to engage corresponding threadsin a cast iron breech section A, this breech section being inserted in thel openingV 22 in the stock part 11 from the top. This stockl part 11 may be made of any suitable economical material such Vas molded plasticcomposition, as alsomay the stock 12, and these are preferably modeled after the armyrifle as closely as possible.

The tube maybe further secured in position bymeans such as a set screw 26 threaded through the under side of the barrel andhaving a pointed end engaging an indentation or recess in the wall of the tube.

The rod 28Vhas its forward end slidably held in'a central bore or passage in a plug 27 held permanently in the bore of the gun, conveniently by an annular groove in the plug engaged by an annular rib in the bore lining and this rod has at its inner end an enlarged head 30 against which bears one end of a. long and relatively Aweak spiral spring 29 which encircles the rod and bears against the plug or block 2'? at the opposite The spring'is of just suiicient tension to draw the rod back into the bore after it has The front end'of the rod is adapted to have a plurality of-tips-of different character detachahly and inter'changeably4 connected thereto, and-'a 'convenient means of effecting such connection is to thread its outer end to engage correspondingly screw threadedsockets the` tips as clearly shown Figs. `1 and. Y

In order to project the rod 28 it must be struck by a. blow sufficient to overcome the `Specification of Letters lPatent, Patented 211111921-, 1921.

propelled by a spring`49 of 'a strength sufhl'f Vcient to give a blow which 28 against the tension of spring 29. I prefer to -use .in my dummy gun, dummy cartridges such as shown at 5l, each Comprising a member having an exterior ofcartridge shape, and having' in place of the usual primer a sliding rod or plunger .52 extending completely through a central longitudinal openf ing in the cartridge and having one end adaptedto contact'with the head 80 of rod 28 and the other end to receive the impact of plunger 41. A portion of the central opening isA enlarged to receive a springfwhich encircles the rod 52 `'and bears at one vend against the annular shoulder formedby said enlargement and at its other end aga-inst an annular'shoulder or enlargement onthe rod thereby ho-lding said rod normally retracted.

,To manipulate the cartridges I may provide a slidable breech bolt 89having a suitable operating handle40 and which breech bolt serves as a container for the spring 49. The' breech bolt has an ejector`45 at its forward end for engaging the rim of the car-y tridge and withdrawing `and ejecting it in lthe usual manner.` The, spring49 encircles a rodv48 forming a reduced extension of the plunger, and lbears at one end on the 'plunger and at the other end against the end wall 504 The plunger Ahas a r of the breech bolt. i shoulder 47 designed, when'retracted, toengage .a locking .projection on the trigger piece 37 which is pressed into engaging position by spring 38, the usual trigger guard` being shown at 36.

When it is desired to use the gun as a repeating rifle and supposing it to be in readiness for firing with the parts in the yposition shown in Fig. l thebreech boltjis drawn back by thehandle 40 which withdraws and ejects the cartridge, andv simultaneously la fresh cartridge is forced into" position by` the supporting plate 60 pressed upward by lever 57 under the action of spring 58.l As the breech bolt is drawn back the plunger moves back with it until the shoulder 4'? is engaged :by the trigger. The shoving forward of the breech bolt forces the fresh cartridge into. firing position -and compresses the spring 49 dueto the fact thatthe plunger is held against Vforward movement by the trigger. i The pulling of the trigger then releases the plunger which is drawn forward by the spring and through rod 52 delivers a blow to rod 28 suiiicient to projectthe lat ter from thebore of the gun as heretofore explained. Y Y f In order that the `gun .may be operated without moving the cartridges I provide the nod 48 of the breech bolt withY a rockingv will project rod,

-means for handle 42 at its rear end by which the plunger may be drawn back and the spring lcompressed without moving the breech bolt.

v.it is desired to use the gun for single shots only, no cartridges are inserted in the niagazine, anda cartridge Ywith cut away rim whichthe extractor 45 cannot engage Vis placedin Lthe chamber toV maintain connection between firing plunger and rod.

To prevent the firing of al live cartridge, should one be placedY in the gun, the head ofthe plunger is made of Vsuch shape as to be ineffective on the cartridge primer.

vAs hereinbefore stated the rod 28 is designed to carry a removable tip, enabling various kinds to be used. In F ig. -l I have shown a tip having a barb on which may be applied a rubber head when a pricking point is not desired.

' Thistip may be removed and tip 65 substituted, having a split portion to hold a pencil lead 66.

, In Fig. 6 I have shown means for making an ink mark on the target which comprises atip 67`ha-ving a seat face or hammer like l. As an article of manufacture a dummy gun having a member extensible from the barrel thereof and spring means holding said member normally retracted. Y

2.As an article of manufacture a dummy gun having a member eXtensible from the 'l'arrel thereof, spring means holding said member normallyretracted and'spring hamgive forward move-V mer means act-liable to incnt to "said member.

3. As an article of manufacture a dummy extensible target and a dummy blow of said gun having-a limitedly striking rod, a spring hammer cartridge for transmitting the spring hammer to said rod.

4. Asanarticle of manufacture a dummy gun having a target striking member actuable by a dummy cartridge.

5. A device of the class described including dummycartridge firing mechanism, said mechanism including means forpreventing the firing of a live cartridge. r

6. In combination with a target practice .i'od, printing means carried on the` rod,

means for inking the printing means and automatically removing and replacing the inking means in inking position upon extension and retraction of the rod.
